Soldiers' brain scans show PTS

Scientists using imaging scans on soldiers have identified brain patterns that signal post-traumatic stress, a finding they said Friday might ultimately help diagnose the disorder sooner.

The scans of 42 U.S. soldiers who had served in Iraq or Afghanistan in the recent past showed that, compared with healthy veterans, those suffering from post-traumatic stress disorder had marked differences in some brain activity.

The study was presented at the World Psychiatric Assn. Congress in Italy.
